The AD8367 is more than twice as expensive as the PE4312, though the AD8367 datasheet does show how to implement AGC with it using 2 additional chips. So if you want to include AGC with programmable attenuation, the AD8367 may be the way to go.
However, for less than the cost of a single AD8367 you can put two PE3412's in series to get attenuation up to 62dB.
Not sure what the best trade-off is. Depends on your needs and price range, I guess.
